UNITED STATES PATENT OFFICE STONE MUOKJNG MACHINE Peter Yannes, Hazleton, Pa. 7 Application October 9, 1935, Serial No. 44,150 18 Claims. (01.198-14) This invention relates to new and useful improvements in a stone mucking machine.

The invention has for an object the construction of a device as mentioned which is adapted to be placed within the tunnel of a mine and collect material from the tunnel to the front of it, and discharge this material within a mine car.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

The stone mucking machine, according to this invention, comprises a carriage consisting of a platform III, a frame II, and a reinforcement structural strut I2. The platform I is supported upon wheels 13 which engage tracks l4 laid upon the floor l of a tunnel 16 of a mine. A trough I1 is supported upon the frame II and connects with a continuation trough l 8 supported upon the structural strut [2. The trough H is pivotally mounted by a pintle l9 so that it may be pivoted to an inoperative position, as indiline cated by the dot and dash lines 11'. In this latter position it rests upon the frame H. In the operative position the trough l1 extends from the ground at the front to the trough I8. A mine car 20, also adapted to run on the tracks 5 I4, is connected'with the platform l0 and is located beneath the trough 18 so that the stone muck may be discharged therein.

A pusher cart 2! islocated within the front end of the trough IT. A relay pusher cart 22 is 10 cated in the top horizontal trough l8 and is' associated with mechanism by which all stone muck delivered by the pusher cart 2| may be pushed along as hereinafter further described.

A mechanical scoop is provided for lifting the stone muck into the'front end of the. trough I1. This mechanical scoop consists of a scoop '23 which has .a leading edge 24 for engaging the ground and which has a handle 25 extended from the top thereof. The handle 25 is provided with a pulley 26 beneath which a cable 21 passes. This cable is attached at one end 28 upon the side of the'trough H. The other end of the cable is guided by pulleys 29 mounted on the trough opposite the end 28 and connects with a drum 3!! uponone end of the shaft of a motor 3|. On the other'end of the motor shaft there is another drum 32 upon which there is wound one end of a cable 33.' This cable 33 extends over guide pulleys 34- mounted on the trough l1, and over a pulley 35 on the end wall of the tunnel l6.

A clutch is associated with the motor 3| and comprises a handle 36pivotally mounted at one end and connected with an operator rod 31 controlling the clutch jaws 38 and 38. The ar- 5 rangement is such that when one clutch jaw is engaged, the other one is disengaged. Thus, the rotations from the motor 3! are transmitted to one or the other of the drums. (The details of the clutch will not be given in this specification since they form no part of the invention.) When the drum 30 rotates, the scoop 23 will be drawn towards the trough l1, and when the drum32 rotates the scoop will be drawn back to the ground.

Thefrontend of the troughll is provided with an inclined plank 39 along which the stone muck may be forced by the scoop 23 until the scoop has reached a position indicated by the dot and dash lines 23 in Fig. 3;" In this latter position all the material to the front of the scoop will have been discharged into the trough". H

A mechanism is provided for moving the pusher car 2! up the trough I! to discharge said material on the relay pusher cart 22, and after edges of the pawl-6|.

it reaches the top, returning automatically to its original position. This mechanism consists of an electric motor 48 which is mounted on the platform I!) and which has cranks 4| attached on the shaft thereof. These cranks 4| are connected by connecting rods 52 to a pair of triangular plates 43 which are pivotally supported at their centers 44 on the sides of the trough I! with the rods 44. Cables 46 and 45 are attached on the top and bottom ends-of the plate 43 and extend over pulleys 41 which are mounted by rods 41' on the sides of the trough. These cables connect at their ends with vertical strips 49 pivotally mounted at their centers upon support rods 58. The arrangement is suchthat rotations from the motor 40 will cause'the cables 36 and 45 to oscillate forwards and rearwards. There is a duplicate mechanism on each'side of the trough, as clearly shown in Figs. 2, fl, etc.

At each side of the trough I? there is a vertical shaft 5| upon whichthere is-mounted a dual drumcompris'i'ng sections 52-and 53. A cable 54 is wound 'on the drum section 52 and extends over guide pulleys=55 and is atta'chedto the back side of the-pusher cart 2|. A cable 56 is wound upon the drum section '53 and extends over guiding-pulleys 51 and is connected to the front of the pusher cart 2|. Thegu'iding pulleys of the cables are so arranged that when the shaft 5| is turned in one direction, the pusher cart will be moved forwards, and when turned in the opposite direction, 'it will move rearwards. The cables and the guiding pulleys are so arranged that the pusher cart 2 I may travel upwards upon the trough H to a position, indicated by the full lines in Fig. 5, in which it discharges on the horizontal relay pusher cart 22.

There is a gear"59"secured*upon each end of the shafts 5|. This gear is adapted to be engaged by a ratchet operated "by the oscillating cables '46 and 45 to cause theshaft to rotate in one direction or the other,"depending upon the adjustment of a control. "More particularly, in Fig. 9 the control is 'shown in detail arranged in a neutral position, one in which the oscillations are not transmitted. The transmitting device consists of a block fixedly mounted upon the oscillating-cable and carrying a triangular shaped pawl 5| which 'is'pivotally'mounted at the point-62. The apex of the pawl"6| engages against-a spherical 'member'63 urged into operative position by a spring 64. The spherical member 63 is arranged upon the end of a plunger 65 slidablein a standard 66 on the block58. A control pawl 61 is pivotally mounted intermediate of its ends by a pawl 68 and arranged in a manner so that its forward end is adapted to engage a shoulder 69 upon the pawl 6| to hold the pawl in the neutral position. A cable 10 connects with the pawl 61 to pivot the pawl to an inoperative position. A spring H urges the pawl 51 into the operative position.

The cables 18, from each of the pawls 61, connect with cables 12 connecting-with a control lever 13. Thus, when the control lever 13 is pivoted manually the pawls 51 are moved to the inoperative position. In the inoperative (the lowerposition) of the pawl 61 the pawl 6| will automatically pivot to the forward position'indicated in Fig. 10. Carried on the pawls 6| there are two-way ratchets urged into operative positions by a spring 16. These ratchets are equipped with projecting pins '11 engaged by'the Thus when the pawl is pivoted to the forward position, as shownin Fig.

10, one of the ratchets 15 will be lifted to an inoperative position, while the other ratchet I5 will be urged by the spring 16 into operative position.

Oscillations of the cables (46 and 46') will now be transmitted by the engaged ratchet to rotate the gears 59 and thus the shafts 5|. The shafts 5| are now turning so as to wind the cable 56 on the drum 53 to move the pusher cart 2| forwards. The cable 54 is now unwinding from the drum section 52. The pusher cart -2| will move slowly forwards and advance all of the material inthe trough I! to the front of it.

The pusher cart 2| comprises a frame having -=a plate on the front thereof, and at the rear pro- -'|8--as clearly shown in Fig. 5. It is thus possible for the pusher cart to assume the position shown in Fig. 5 in which the material is completely discharged on the relay-pusher cart 22.

The .paWlsBI at the top -and at the'bottomof each-of the shafts 5| are connected for unitary motion by a wire frame 19' and 19. This wire frame has eye portions fill-through which-the cables 54 and 56 pass. Stops 8| (see Fig. 8) are attached on the cables near the inner ends thereof and are adapted to engage against the ends of springs 82 mounted on the cables adjacent the eye portions. taneously pivot the pawls'Bi for automatically reversing the forward motion of the. pusher cart, as hereinafter further described.

From the position of the pawl 6| shown in Fig. 10, which is the position in which the pusher cart is moving forwards; the pawls will bev pivoted to the position shown in'Fig. 11 by .theaction of the stops 8|. More particularly, when the pusher cart'2l has reached the position shown in Fig. 5, the stops 3| on the unwound cable will operate the frame of the pawls-andgpivot the pawls.

The pawls will be retained in the new position by the action of the spherical member 63 and the spring 64. In the newpivoted position of each pawl 6| the ratchets T5, whichwere'peripherally engaged with thegears 59 will be out of engagement, and the previously inoperative ratchets placed into-engagement. The'osc'illation of the cables 46 and 46 will now be transmitted to rotate the shaft 5| in the opposite direction. This causes the-pusher "cart to move rearwards. When the pusher cart has reached the complete rear position,-that is, the initial position shown in Fig. 3, one of thestops 8l will-again engage the frames 19 of thepawls'lil and-pivot the pawls to theneutral -or initial positions illustrated' in Fig. 9. The operation of the pusher cart is now-at an endand will. not be resumed, except if the lever"'|3 is-again manually operated.

The pusher-cart -22 very-similar in construction to the pusher cart 2| and is operated by mechanism very similarto the mechanismoperating the pusher cart 2|. More particularly,

cables 36 and 45 areconnected'with the-pivoted memb-e'rs'59' and"- are extended along the sides of the trough I8 and are connected with other pivoted members 83. The arrangementis such that the oscillating of the cables 46'and 46' :are directlytransmitted to'the cables 46 and 46 "Vertical shafts 84 are mounted upon the sides of the trough l8 and support drums 85and ,85. Cables 8! are mounted on thejdrums 85 and extend over guiding rollers 88 and connect with the spindles It is thuspossible to simul- 89 of the rollers 90 of the traits 9| of the pusher cart 22.

Another cable SZcQnnects'Withthe spindles 89 and extends over guiding pulleys 93, 93, etc., and are wound upon the drums 86. The arrangement is such that when the shaft 84 is turned in one direction, the relay pusher cart 22 will be moved forwards from its initial position which is illustrated in Fig. 5. When the shafts 84 are turned in the opposite direction, the pusher cart 22 will move rearwards until it has reached the initial position .which isshown in Fig. 5. The mechanism for turning the shafts 85 in one direction or the other is identical to the mechanism used in turning the shafts 5|. This mechanism is clearly shown in Figs. 3 and 4 and the corresponding parts thereof may be recognized by the same reference numerals.

The pawls SI of the second shaft turning mechanism are connected by frames 19 which frames are provided with eye members 8%. The cables 81 and 92 respectively pass through these eye members for automatically operating the pawls as previously described. An automatic device is provided for moving the pawls SI of the second shaft operating mechanism to the forward operating position and consists of a cable 95 which is connected with the pawls B'i of the second shaft operating mechanism. These cables 95 are extended over guiding pulleys 96 and terminate through guiding blocks 9! at which points they are connected with springs 98 connected with the free ends of levers 99. These levers are pivotally mounted and have their extremities engaging over and in the vicinity of the cables 56. Thus, when the stops 8| of the cables 56 operate the pawls of the first mechanism to reverse the travel of the pusher cart, the levers 99 will be simultaneously operated by the stops 8| to set the pawls 6| of the second mechanism into forward operation. Then, as the pusher cart 2| returns to its initial positions, the pusher cart 22 will be moved forwards to relay the movement of the material to the train car 20.

The trough i! may be pivoted to the horizontal position, indicated by the dot and dash lines, by the operation of a lazy tong structure shown in Figs. 1 and 2. This lazy tong structure includes several relays I00 pivotally connected with a stationary frame and with the trough, and operated by a screw shaft ||l|. This screw shaft is provided with a handle I02 by which it may be rotated. The screw shaft |0| has right and left hand threads on sections thereof. When the handle I02 is turned the arms H10 of the lazy tong structure will be spread to collapse the structure, or may be contracted to extend the structure. Thus, it is possible to move the rear end of the trough |1 upwards or downwards. The car 20 may have any number of traps in the top thereof through which the material which is advanced by the relay pusher carts may be discharged. The top trough I! may continue horizontally through any distance so that the material may be discharged to other trains upon the track I4.

The operation of the device is as follows:-The scoop 23 is operated to move forwards and force the material from the ground of the mine tunnel up the incline 39 of the trough into the trough and to the front of the pusher cart 2 The scoop 23 may move forwards or rearwards by proper operation of the clutch system of the motor 3|. When sufficient material has been discharged into the trough the pusher cart 2| is set into operation by moving the lever 13. This causesthe pawls 6| of the first pusher cart mechanism to move to the forward'positions, asshown in full lines in Fig. 10. I

, The motor 40 is continually operating to pivot the plates 43 and cause the cables, 46 and 46 and 46 to be continually oscillating. In the forward position of the pawl 6| the oscillations of the cables will be transmitted to rotate the shafts 5| and cause the pusher cart 2| to slowly move up the trough When the pusher cart has reached the complete top position shown in Fig; 5, it will have discharged all of its material on the pusher cart 22. In this position the stops 8| cause the pivoting of the pawls 5| to the backward position shown in Fig. 11. This automatically causes the pusher cart 2| to, start moving rearwards. Simultaneously, with the reversing of the pusher cart 2|, the pusher cart 22 is'set into operation by the stops 8| engaging the levers 99. The pusher cart 22 will now start ad-' vancing and relay the forward motion of the material discharged by the pusher. cart 2|. In Fig. 6, the pusher cart 22 is shown in an advanced position. When the pusher cart 22 reaches the fully advanced position it will be reversed in its travel by the automatic operation of the'pawls 6| of the relay pusher cart mechanism. It will then return to its original position. There are hooks I05 on the trough I8 in the vicinity of the rearward position of the pusher cart 22 to assist the pusher cart in pivoting intothe closed position shown in Fig. 5. These hooks I05 are counter- Weighted by weights I06 so as to act automatically. I

While I have illustrated and described the preferred embodiment of my invention, it is to'be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modificationscoming within the scope of the invention as defined in the appended claims.
